OF HATTON GARDEN, COUNTY OF GLASS TUBE FOR WATER-GAGES.

SPECIFICATION forming part of Letters Patent No. 349,271, dated September 14, 1886.

Application filed November 28. 1885.

To aZZ whom it may concern.-

Be it known that we, LoUIs JOHN ORossLEY, carpet manufacturer, and RICHARD HANSON,

engineer, both of Dean Olough Mills, Halifax,

of the water more clearly visible, they have been made of clear glass with a longitudinal stripe of white or colored enamel at the rear of the bore thereof, providing a backing'of such a width as to cause the whole'body of water in the-tube to appear of the same color as that of the enamel stripe. Theyhave also been made with a comparatively narrow stripe of red or other bi -i glit-col ored enamel on a broader back ground or backing of white enamel. These two arrangements have proved greatly superior in use to gage-glasses made entirel of clear glass. We have, however, succeeded in still further improving the manufacture of gageglasses.

\Ve are aware that it has been proposed to divide the backing of a gage for the purpose of admitting light to enable the height of the liquid to be seen; but in such case the stripes thus formed have extended so far toward the front of the tube as to be useless for our purpose. In our present invention we simply divide the backing, shown in our Letters Patent No. 182,192, dated September 12, 1876, so as to leave a clear stripe. or stripes of clear glass without increasing the width of the backing, so that the liquid contained in the tube may appear of greater width than the backing, and the gage be adapted for use, as hereinafter described.

Our invention is represented in the accompanyin drawings, of which Figures 1 and 2 represent elevations of part of a gageglass seen from different points of view, and Fig. 3 is a cross Serial No. 18 1.206. (N0 model.)

section of the same, and Fig. 4 isa cross-section of another gagcglass.

According to our invention, we apply to the rear of the bore of the gage-glass tube a two or more longitudinal stripes, I), of enamel, which are separated from each other by'a space or division, a, of clear glass, thus forming a divided backing. This backing is of less width than the tube, for the object hereinafter stated. These enamel stripes b may be all of the same color or they may be of different colors. WVe however prefer to make them of white enamel, as by so doing the gage-glass will stand better in use than when employing other and different colored enamels. By these means, when two strips, 1), of enamel are employed, and the gage-glass a is seen from the front in the direction of the arrow 0, it will have the appearance above the Water-line of a couple of comparatively broad stripes, b, of enamel, divided from each other by a narrow division, a, of clear glass. Astripe, a, of clear glass will be clearly seen at the outer edge of each enamel stripe, while below the water-line there will be seen down the center thereof a stripe, a, of clear glass much broader than the part thereof shown above the liquid, and on each side of such central stripe, a, of clear glass the tube will appear to be lined to the edge thereof with enamel I). Vhen, however, such gage-glass is seen at a certain considerable angle from either side thereofsay in the direction of the arrow (Zit will show below the water-line one broad band, I), of enamel, bounded on each edge with a narrow stripe, a, of clear glass, while above the water-line there will be seen two stripes, b, of enamel, of uncqual widths, divided from each other and bounded on their outer edges with stripes a of clear glass, of unequal widths, and along the entire length of the gage-glass on one side thereof will be seen, apparently on the (iXtQ- rior thereof, a narrow stripe of enamel. At the intermediate points of view the variation in appearance presented by the gage-tube above and below the water-line is equally distinct. By making these stripes of white enamel the gage-glass will stand better in use than when employing different-colored enamels. \Vhen employing more than two stripes of enamel, we preferably make them narrow and of about the same width as that of the clear glass between them, as shown at Fig. 4, and we also preferably employ such a number of these stripes as will extend about from a third to nearly half round the circumference of the glass tube. By this last arrangement the tube has nearly the same appearance, whether seen from the immediate front or from somewhat wide angles atthe sides thereof.

The width of the enamel stripes I) and of the clear glass between them may be somewhat varied.

Having now particularly described and as eertained the nature of our said invention and in what manner the same is to be performed, we declare that what we elai m is A water-gage glass tube provided with a backing formed of stripes of white or eolored enamel having a elear glass space between \Vitnesses to the signatures of the said Louis .Tohn (,rossley and Richard Hanson:
